Her grumpy expression made her popular all over the web.
Her actual name is Tardar Sauce (deliberately spelled incorrectly).
Her real name stemmed from having dark spots in her fur; her owner's daughter said the fur looked like tartar sauce.
She has an Instagram profile, a Twitter account and a Facebook page.
At SXSW Interactive, fans waited up to three hours to meet her (with the lineup being three blocks long).
She can beat out Mikayla Mahoney for the most 'sourpuss' facial expression.

Why she might not be annoying

She is smaller-sized cat, almost dwarfish in proportions.
Fans can buy her souvenir t-shirts online.
As of the early spring 2013, her Facebook page drew 768,000 'Likes.'
She has appeared on 'Good Morning America' and 'Anderson Live.
For the SXSW Interactive event, Friskies paid for flying her first class flight, luxurious private suite, chauffeur, bottled water and unlimited kitty treats. (Source: TMZ)
